fax sharing printing

Hy

I have SBS 2000 with a fax server instaled. When instaling
the fax client on a windows XP system I encounter a
problem.

This is how is suppose to be done

"To configure Modem Sharing Client:
Open a command prompt, and then type the following command,
where server_name is the name of your server:

netmodem view \\server_name
NOTE: If you have created a modem pool, this pool is
listed. If you did not create any modem pools, you must
create one on the server.
Type the following text, where server_name is the name of
your server and pool is the name of the pool that is
displayed in step 1:

netmodem use * \\server_name\pool
You receive confirmation of a successful attachment and a
report of the local communications (COM) port that is being
used.


Type the following command:

net stop serrdr
Type the following command, and then close the command
prompt window:

net start serrdr
Double-click Phone and Modem Options in Control Panel.
Click the Modems tab, and then click Add.
After the Add Hardware Wizard starts, click Next.
Click Next, and then click the modem that your server is
using from the list that is displayed.
Click Selected Ports, and then click the port that is
displayed in step 2.
Click Next, and then click Finish.
To verify that Shared Modem Client is working, right-click
the modem, click Properties, click the Diagnostics tab, and
then click Query Modem

When instaling the modem the ports specified in step 2 are
not an option in add new modem window and i can select only
com ports already use. For example on a PC with com 1
instaled, the netmodem is used on com2 but i can't select
com 2 when instaling a new modem
